”Thank you for designing a product that actually works well. I have been processing taunna (arrasta) tailings from areas in Mexico. These small operations loose up to 70% of their gold and throw 10-15% of their mercury into the tailing piles. Your table not only catches the lost gold, but captures almost all of the mercury.” Thanks!

“Thanks for the great tips…we are getting to know the table (M8s) - and implementing a lot of what you have said has helped enormously. We have quite a bit of pyrite at the moment but can get a clear line between gold, pyrite, and ballmill steel/magnetite. We are still getting a lot of mercury coated gold in the system and amalgam balls as the previous owner put in quite a bit into the ball mills. We see this on the tables. We are having a few issues on getting screening right. We notice in the book that the 4 tables are set at very narrow screening intervals. At the moment we have 0.25-1.00m going over the table and it seems to work although we find a bit of the mercury gold in among the sand (top area) and not getting to the front. Guess it is because some of this has been flattened by the ball mills and partly digested by the mercury. So overall happy so far on table runs, we’re just kicking in the bigger ball mills so will let you know on results of more of the commercial sized production runs. ”

“The Wave Table is one of the best, if not the best, I’ve ever owned, and gets the real fine gold mostly on the first pass, but some of the ore I’m working with has a lot of cons in it, so I’m having to run some of it 2 or 3 times to really get all I think there is in it. I had to re-bolt it to the floor in my shop to keep down vibration…it works very well now that I have that done. ”

“Just wanted to let you folks know that I finally got a chance to run about 80 lb of Nome concentrates through the M4. Had already run it through a gold wheel and the wheel did surprisingly well, but the M4 pulled some mighty fine gold out that the wheel missed, not a lot, but the M4 handled the material a lot faster and easier. Can’t wait to get it up to Nome this summer. ”
Harold, Alaska
 
“Since I unpacked my table, I’ve run it about 4 or 5 hours getting used to it. I am quite satisfied with the first results and the first recovery tests are positive. I am certain already that your table is the right recovery system that I was looking for and t his equipment will be very useful in my gold room. As you probably remember, I need your table for daily ‘clean ups’ of about 350 lbs of cons coming from my concentrator. The separation is effective and rapid, quite surprising I must say. ”

““Let me explain, for the last two years I am living on my mine site. Indeed, after so many years and more than 1200 hours ( I have precise records) using your M8 table I am still a very satisfied and happy wave table user. I sincerely believe that your wave table is a "must" for primary (hard rock) mining. The finer the gold, the better the table behaves. To me it is always a surprise to see how microscopic gold comes out first. Often I get a "cloud" of floating gold on the surface of the water. Luckily this floating gold gets back to the bottom when it reaches the hopper barrier of feeding water. The table that I purchased from you is now presently used by my son on his alluvial mine. I managed to recuperate the second table that you've sold to Christian at the time. My son has coarse gold and recuperates about 80 to 85% of his gold on the M8. It is a fact that these tables work perfectly with microscopic and fine gold, they don't really perform at 100 % with coarse gold.” Warmest regards ”

“Nancy, “the 2 M7 Micron Wave tables that we are using have performed flawlessly. Due to the density of the feed and the continuous operation, we had to make a few very minor changes to the tables. One table is being used to recover metal values that our other recovery processes missed. The other M7 is being used to clean up the mids from a full size Diester table. Both tables have been running 24/7 since 1996 with no breakdowns! The M7 tables are very efficient as far as low water consumption and are able to recover metal in the range of 5-44 microns, something that our large tables have trouble doing. The tables are very operator friendly and inexpensive to maintain. Two of our tables are being used to make a clean product (tungsten carbide) of minus 400 mesh material. The feed rate for each table is about 75 lbs. per hour. The other table is used to scalp the tailings from 4 full size Wilfley tables and it has a feed rate of about 200 lbs. per hour.”

“Low water consumption and high grade micro mineral output. Rather perfect lab/production device to work in the field away from any sufficient water sources. That's the way to go! From all Recovery devices I have reviewed so far by distance the M7 is the most convincing one.”

“Attached pic shows your M7 set up on a rather large concrete base. It works well, developing a black sands line within 12-17 seconds after feeding a sample. I don’t think I’ll ever pan again”

“First calibration/commissioning run of a single table. ”

“I have performed clean ups of used/spent activated carbon on a M7/M8 Wave Table(WT) and the results were ‘mind blowing’ !....to say the least. The owners of the largest carbon stripping operation (toll treatment) in Australia brought me some samples and I ran them over my M8. All they wanted, was to see if the M8 could separate the grit out of the carbon. Everyone’s eyes popped out when they saw how easily the M8 separated the grit from the carbon granules - to such an extent that the plant operator was astonished at how much gold there was remaining in his large accumulation of spent carbon! In this grit was heaps of gold! ”

“Dear Nancy, we are testing currently different mineral ores (gold, wolframite, tantalite). We will keep you informed about the results. ”

“Hi Nancy, Thanks very much for the follow-up note. As an aside: I particularly like that you had the right table for our voltage in stock, and that we received it at the project in Paraguay within six days of our order. In getting our project underway, most articles have not been acquired so easily. The table has been working well for us. I helped the gold room guys set it up myself, and I have operated the table personally for a few days. The gold room guys are using it all the time. I liked that it is easy to set up and to run. We can adjust the 'hit' easily, and the concentrating performance responds to those adjustments. I learned in the first few minutes of playing with it that by pushing or pulling against the table, you can change the 'hit' strength for a brief period, which can be handy sometimes. We are struggling a bit to separate larger grains of hematite from our finer gold grains. The coarse hematite typically wants to follow the gold. (Our material is already gravity concentrate from Falcon concentrators, that has then passed twice over a Deister table before getting to the small wave-table). We think the way to resolve this better is by doing a lot more grain-size sorting before we get onto the wave table (20 mesh, 40 mesh, 80 mesh....). Anyway, the table has been easy to use and is pretty fast at bumping the gold to the leading edge. It's working pretty well for us. ”
Best regards, Miles, Paraguay
 
“The M7 is an amazing piece of equipment. It does everything you said it would…it now makes a lot of other pieces of equipment obsolete and is going to change the way we (sample) the ground. We are seeing stuff that we could not get with the pan. Even using the table to say yes/no as to if its worth sending any sample to the lab justifies its use. ”

“I ran the old type tables and they just frankly, didn’t inspire me. Your table does! Not only is the theory fabulous…it makes the operator strive to get the BEST separation possible. So…not only do you have a successful run..you feel damn good about it. ”
Cheryl C, Oregon
 
“The first test we ran on the M8 got a 70% recovery of the gold present. The WT had just be set up, the ore was not ground properly, and we still got a good result. I am confident that I will get at least 75% recovery rate when set up properly.””
Hans, Germany
 
“There are many types of shaking tables on the market. Almost all have the cons reporting on the table deck in a longitudinal direction….whereas the WT has the cons reporting transversely (across the deck). This is a great advantage as it provides a cleaner separation, higher recovery of for example, gold (particularly, fine gold)….and allows gold to accumulate on the deck which is advantageous in clean-ups when you wish to wet vacuum off the gold. The general action of the Wave Table is superior to the other shaking tables. Hence, higher recoveries of the very fine gold are achieved. There are many other advantages…such as size, lower water usage, lower power usage and lower overall cost per unit of throughput. For the above reasons, I personally use WTs in my two gold mines in Australia and they work extremely well.””
